Background and Objective: Hospital waste water due to infectious organisms and other risk factors is important. In this study, the possibility of coliform bacteria removal from hospital waste water using ozone separately and combining with hydrogen peroxide (H2O2 + O3) as a pre-treatment was investigated. Material and Methods: This is an experimental study that in the second moiety of 1392 i...

Values of blood gas, serum chloride, and potassium were tabulated for 21 dairy cows with coliform mastitis. Severe cases showed marked clinical signs such as loss of appetite and depression of digestive tract motility, and metabolic alkalosis such as an increase in blood pH, hypochloremia and hypokalemia compared with normal and mild cases (p < 0.01). The results showed that metabolic alkalosis...

Bacterial whole-cell biosensors were used to measure the concentration of chlortetracycline (CTC) in the feces of pigs. In this study, the Escherichia coli biosensor used has a detection limit of 0.03 mg/kg CTC in pig feces. The tetracycline concentration was correlated with the appearance and maintenance of fecal coliform bacteria resistant to tetracycline. Initially, large quantities of water...

Escherichia coli, Klebsiella pneumoniae, and Enterobacter aerogenes are recognized as the most common coliforms in bovine mastitis (Bannerman et al., 2003). Exposure of uninfected quarters to coliform pathogens occur primarily between milkings and, secondarily, during milking procedures and dry period. Coliform pathogens are essentially opportunistic. Their primary reservoir in transmission is ...

Data from a study of five stations on the Spoon River, Ill., during June 1971 through May 1973 were analyzed for compliance with Illinois Pollution Control Board's water quality standards of a geometric mean limitation of 200 fecal coliforms per 100 ml. This bacterial limit was achieved about 20% of the time during June 1971 through May 1972, and was never achieved during June 1972 through May ...

The Honolulu Board of Water Supply (HBWS) selectively chlorinates half of its groundwater supply to provide drinking water that meets the Total Coliform Rule. The objective of this study was to determine whether the groundwater sources used by HBWS are vulnerable to contamination with fecal matter and would require routine disinfection. Larger volumes (1,000 mL) of samples from groundwater and ...
